Title: Voltage controlled oscillator
IPC: H03K3/354
Filed: 1992-03-17
Abstract: PURPOSE:To attain the oscillation over a wide frequency range by providing a MOS transistor(TR) connecting in series with a 2nd power supply of a complementary inverter circuit and whose gate receives an oscillation control signal. CONSTITUTION:Inverter circuits 1-4 connected in series in a ring form and a NAND circuit 5 form a ring oscillator. The circuit 5 is a circuit using an oscillation circuit signal CR to control the oscillation and its stop, and when the signal CR reaches logical '1' and the oscillation is started, the circuit 5 acts like an inverter circuit. An output OUT of the voltage controlled oscillator is outputted via an inverter 16 connecting to a node K5. An oscillating frequency of the ring oscillator depends on a delay time per stage of the circuits 1-4, 5 and the delay time of each inverter circuit varies with a voltage of an oscillation control signal IN. Thus, the oscillation over a wide frequency range is attained.

Title: Device for detecting defect on disk surface
Inventor: HARAMURA SHINICHIROU
IPC: G01N21/94
Filed: 1982-04-08
Abstract: PURPOSE:To ensure the simultaneous detection of defects on the surface of the disk having many tracks, wherein synchronizing signals are recorded, by making the spot shape of laser light long in the radial direction of the disk, and inclining the shape with respect to the radial direction. CONSTITUTION:The spot 10 of the laser light scans the tracks 11 of the disk. The spot is reflected by the disk surface and the defects on the disk surface is detected. The shape of the spot 10 of the laser light is long in the radial direction of the disk. Many defects on the many tracks 11 can be simultaneously detected. The spot shape of the laser light is inclined with respect to the radial direction. Therefore, even though the periodic signal such as the synchronizing signal is recorded, periodic signal pit is hard to operate as a diffraction lattice, and only the signals for the defects can be detected.

Filed: 1982-04-09
Abstract: PURPOSE:To generate CO2 laser beam with a high efficiency bu irradiating a microwave generated by a magnetron into a resonator of cavity which is hermetically sealed and comprises a reflectors at both ends of inside. CONSTITUTION:A generator is composed of a laser excitation power supply 1 and a resonator 2. A microwave is transmitted by a coaxial cable 1a and the mixed gas of N2 and He containing the CO2 gas led into the resonator 2 from the lead-in port 5 and is led-out from the lead-out port 6. Thereby, the mixed gas circulates. A cooler 7 is provided at the exteral side of resonator 2 and the cooling liquid is thereby circulated. A microwave generated by a magnetron is irradiated to a resonant tube 2 from an irradiator 3. Thereby, the microwave shows resonance phenomenon with CO2 which circulates within the ferromagnetic field formed in the resonator. A laser beam is thus generated as a result of resonance and it is extracted as a standing wave by repetition of reflection by the reflectors 4, 4' at the inside of resonator.

Title: Multilayered ceramic circuit board manufacturing method
Inventor: HAMANO AKIHIRO
IPC: C04B41/88
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To remove binder from a multilayered ceramic circuit board in a short time at a low temp., without using water vapor by removing binder from laminated green sheets having printed circuit patterns in an inert gas atmosphere contg. CO2 and baking in an inert gas atmosphere. SOLUTION: In an inert gas atmosphere contg. carbon dioxide, the binder removing treatment is done to result in that carbon remaining during the ceramic forming is converted into a carbon monoxide gas, thus removing C from the ceramic molding, without oxidizing a metal conductor layer. Since the oxidation power of CO2 is less than that of O2 , oxidation of the metal conductor by CO2 little progresses. When CO2 is added to a nonoxidative gas atmosphere, such trouble as dewing does not occur and there is no limit of the content of added CO2 . Thus it is possible to remove the binder in a short time at a lower temp., without using water vapor.

Filed: 1983-04-04
Abstract: PURPOSE:To form a focusing device which is capable of adjusting a start time of a focus detecting operationin accordance with a focus state by shortening a time interval for detecting a focus, as compared with the case when a focus state is far in case when a focus state of an image pickup optical system is close to the focusing state. CONSTITUTION:When a start signal STT of focusing control is inputted to a focusing control means 6, focusing is started, and first of all, a projecting signal d1 is sent to a light source 7. The light source is lighted by the signal d1, and a light spot is projected to an object 1. This light spot is projected onto a photodetecting part 10, and a position information Cd1 of a light spot 9 is obtained from an amplifying means 5. Because of Cd1>C5, the length td1 of the first TD becomes td1=TD3, and the time interval before the follwing d2 is outputted becomes long. Also, a signal ed1 for controlling a feed quantity of a photographic lens is sent to a driving means 8, and the feed quantity of the photographic lens is changed. When the time elapses by a length td1 after the signal d1 is outputted, the second projecting signal d2 is outputted, and focusing of the second time is started. Since Cd2 is C3<Cd2<C5, td2 is td2=TD2, and shortened. Also, ed2 becomes small, too. In this way, the focusing is repeated.

Title: Delivery device of circulation type grain drier
Inventor: MIYATAKE YOSHIKUNI
IPC: B65G65/44
Filed: 1982-04-09
Abstract: PURPOSE:To make a device small in size and easy for maintenance and inspection by alowing both normal and reverse rotation of a belt conveyor with a slightly wider surface area than a flow port area arranged corresponding to the flow port in the lateral direction of the flow pot in order to provide uniform circulation. CONSTITUTION:The belt conveyor 16 of a delivery device 15 is arranged facing a flow port 9 at a predetermined distance with such a surface area that the grain does not flow down by its weight in relation to the opening area of the flow port 9, and the rotation of a belt 18 is reversed alternately in the lateral direction of the flow port 9. By alternating the rotation of the belt 18 to the left and right, the grain flowing down through the flow port 9 is moved to flow down to the left and right while side pressures are applied alternately from the left and right symmetrically, thereby it flows down uniformly through the left and right grain drying passages 8, 8. In addition, since the amount of left and right movement is larger than the opening width in the lateral direction of the flow port 9, no grain is left behind on the belt 18 at the final delivery, thus the flow quantity per time is invariably made nearly constant.

Abstract: PURPOSE:To perform an accurate measurement in a short time by composing a simple measuring circuit of a DC voltmeter, a control circuit, a variable DC voltage source and a variable capacity diode and controlling an output voltage applied from the variable DC voltage source to the variable capacity diode. CONSTITUTION:The output of a signal source 1 is made zero and the output voltage of an output terminal 23 is measured by a DC voltmeter 7 when a demodulation circuit 2 has no input. A measured valve is outputted from a measuring output terminal 71 to be inputted to the input terminal 81 of a control circuit 8, being made its reference value. The control circuit 8 calculates a difference between the reference value and the measured value of the DC voltage and outputs a control signal corresponding to the difference from an output terminal 82. As a result, the capacity of a variable capacity diode 10 changes and a resonant frequency f0 and an input carrier frequency fc finally agree with each other whereby a synchronization can be obtained.
